Nikon F4

The Nikon F4 is a professional-grade 35mm single-lens reflex (SLR) film camera body manufactured by Nikon from 1988 to 1997. It represented a significant advancement in Nikon's professional camera line, being the first Nikon F-series camera to incorporate autofocus (AF) capabilities. It was designed to accept nearly all Nikon F-mount lenses, including both AF and manual focus lenses, offering compatibility with a wide range of existing optics.

Key features of the Nikon F4 include:

• Autofocus: Utilizing Nikon's AM200 autofocus module, offering single and continuous autofocus modes.
• Matrix Metering: Nikon's advanced matrix metering system, which analyzes light from multiple zones in the scene to determine optimal exposure. It also included center-weighted and spot metering modes.
• Shutter Speed Range: A wide range of shutter speeds from 30 seconds to 1/8000th of a second, plus bulb (B) mode.
• Built-in Motor Drive: Integrated high-speed motor drive capable of shooting up to 5.7 frames per second (with the optional MB-21 battery pack).
• Interchangeable Viewfinders: The F4 allowed for the use of various interchangeable viewfinders, including waist-level finders, magnifying finders, and action finders, catering to different shooting styles and needs.
• User Interface: A combination of dials and buttons allowed for manual control of aperture, shutter speed, and other camera settings.
• Compatibility: Almost complete compatibility with older Nikon F-mount lenses, although metering capabilities varied depending on the lens type. AI and AI-S lenses could be used with stop-down metering.
• Rugged Construction: Built with a durable metal body designed to withstand demanding professional use.
• Power: Operated on four AA batteries (with the standard MB-20 battery pack) or specialized rechargeable battery packs (MB-21, MB-23).

The Nikon F4 was available in several variations, including the F4s (with the MB-21 high-speed battery pack) and the F4e (with the MB-23 battery pack). It was popular among professional photographers and advanced amateurs due to its advanced features, reliability, and compatibility with a vast range of Nikon lenses. It was succeeded by the Nikon F5 in 1996.
